WIRE CABLE Application filed December 26, 1907.

Specification of Letters Patent.

Patented March 23, 1909.

Serial No. 408,219.

To all whom it may concern:

Be it known that l, GARY B. Snrrn, a citizen of the United States,residing at 'Anoka, in the county of Anoka and State of Minnesota, haveinvented a new and useful Wire Cable, of which the following is aspecification.

This invention has relation to wire cables and it consists in the novelconstruction and arrangement of its parts as hereinafter shown anddescribed.

The object of the invention is to provide a cable of the characterindicated which is made up of wire strands helically twisted into cablesections, said sections being helically twisted together and forming thecable. The cable sections are formed with open centers or middles andwhen the said sections are twisted together to form the cable the wiresof the sections at the center or middle of the cable are forced incontact with each other and are distorted slightly out of their relativepositions in the cable sections whereby a cable is formed having thewires in close con tact at its middle and along its entire length withthe wires at its periphery spaced apart thus producing a light cablepossessing strength and flexibility.

In the accompanying drawing: Fi ure 1 is a side elevation of a portionof a ca le with parts broken away. Fig. 2 is a transverse sectional Viewof the cable, and Fig. 3 is a side elevation of one of the strands ofthe ca ble illustrating the configuration of the same when assembled inthe cable.

The cable is made up of the wire strands 1 which in the first instanceare helically wound together forming the cable sections 2. The saidcable sections are open at their cen ters or middle and the strands 1are spaced apart from each other. hen the cable sec tions are thusformed they are straight with substantially circular peripheries. Twocable sections are then helically twisted together as shown in Figs. 1and 2 and during the process of the last said inter-twisting those wirestrands'of the opposite cable sections which bear against the strands ofthe opposite section at the center or middle of the cable are forced inout of the circular alinement of the strands constituting the cablesection so that the adjacent sides of the wire strands at the middle ofthe cable are forced in close contact with each other throughout theentire length of the cable while those wires at the periphery of thecable are spaced apart and maintain the same relative arrangement aswhen the cable sectionswere originally formed. Figs. 1 and 2 of thedrawing illustrate the relative positions of the strands and the cablesection after the cable is formed while Fig. 3 is a sideelevationillustrating the configuration of a single strand of wire inthe cable as made up.

It will be observed. that a line lengthwise of the cable sections anddrawn through the points where the strands come in contact with eachother are helically disposed along the cable sections and that the cablesections in the made up cable are slightly flattened or distorted out ofcircular configuration in cross section as illustrated in Fig. 2.

Having described my invention what I claim as new and desire to secureby Letters- Patent is 1. A cable formed of inter-twisted wires which arein close contact with each other at the center of the cable and spacedfrom each other at the periphery of the cable.

2. A cable consisting of strands helically inter-twisted and being inclose contact with each other at the center of the cable and spaced fromeach other at the periphery thereof.

3. A cable consisting of wire strands twisted into cable sections, saidsections being inter-twisted so that the strands of each section are inclose contact at the middle of the cable and spaced apart at theperiphery thereof.

4. A cable consisting of wire strands helically twisted into cablesections, said cable sections being inter-twisted so that the strands ofeach section at the middle of the cable are in close contact with eachother and spaced apart at the periphery of the cable.

5. A cable consisting of wire strands helically twisted into cablesections, said sections being helically twisted to form the cable thestrands of each section at the middle of the cable being in closecontact nth each other In testimony that 1 claim the foregoing as andspaced apart at the periphery of the my own, I have hereto aHiXed mysignature cable. in the presence of two witnesses.

6. A cable made up of strands formed into GARY B. SMITH. cable sections,said cable sections having Htnesses:

open centers and peripheries distorted out of THOMAS AMLAND, circularalinement at the middle of the cable. J. S. TURNBULL.
